Does my babys father need to sign the adoption papers?
The Bio father does not legally have to sign the birth certificate. If you want the bio father to pay child support it will make it harder for your new partner to adopt your child.,,,he is legally obliged to pay…but it is up to you whether you want him to. Your new partner must get approval from the bio father to adopt, and he will be forced to take a DNA test to check paternity. Or you put the new fathers name on the birth certificate after you get married (small fee) and forget about seeking paternity and child support.
